WebOS: Mojo Debugger State Machine
An hour here an hour there does not make for great progress. I am not an expert in regex so I have resorted to writing unit tests to try and sort out the parsing issues I’ve been getting with the debugger output. Here is a diagram with the state machine for startup, run and pause on breakpoint. This works sort of.
Debugging this is a bit of a chore as the inclusion of the Aptana plugin makes Eclipse really really slow to start up – and of course I am listening to the Aptana javascript editor for breakpoints so I do need it. There might be stuff I can switch off but I haven’t figured out what yet.
Hopefully this weekend I will get a better run and factoring out some of the problems. The good news is that you can set a breakpoint and when it hits the debugger picks this up, gets the stack trace, gets the local variables (or it would do but this state is empty for the moment) before waiting for you to resume. I haven’t put in the step functionality yet although it should be straightforward (in theory anyway).
I am still waiting for Palm to announce their own Eclipse debugger support any day now so I can stop this programming death march (only joking, I think). I guess I’ll just keep going until I get to the point where I get totally stuck.
